摘要:

在自制的装置上,用高能密度的脉冲激光束在高真空中直接溅射红磷和碳、硅、硼或铝粉的混合物,通过激光等离子体反应,产生了十分丰富的XnPm±(X=C,Si,B,Al)二元原子簇,记录了它们的飞行时间质谱.对这些簇离子组分的分析发现,它们的成键和结构因其组成元素的不同而有明显的差异,这些差异反映了它们独特的结构化学行为.

Abstract:

Binary cluster ions of the form of XnPm±(X=C, Si, B, Al) were produced on a home-made apparatus by laser ablating the samples of red phosphorus mixed with carbon, silicon, boron or aluminum powders. Mass distributions of the cluster ions were examined from recorded time-of-flight mass spectra. Their bonding natures and structures were found to be varied with the component elements.

Key words: Binary cluster ions, Mass spectrometry, Laser ablation
